.I <br />.' <br />Mr. Dennis Conn - 3 - January 29, 1987 <br />1. Design for plots and methods and timeframes for soils and <br />vegetation sampling and data analysis should be discussed. <br />2. Plot size should be as Large as is practical. A minimum size <br />is 2,500 ft2 each. <br />3. The design for the research ,plots should be statistically <br />correct with 3 replications and randomized treatments. <br />4. Treatments recommended are b inch cover, 12 inch cover, 24 inch <br />cover and 48 inch cover. <br />5. All major aspects (E, W, N, S) should have a separate series of <br />treatments. The reason for this is that moisture conditions <br />vary greatly between aspects. A south aspect in general <br />requires a greater soil cover than a north aspect. Fach aspect <br />may have to be compared to a separate reference area. <br />6. The plots must be seeded, mulched and fertilized according to <br />the approved reclamation plan. <br />7. Cover by species should be measured to statistical adequacy <br />each year. The cover information then should be compare'. *_o <br />the historic reference area data. Production Clippings should <br />be done years 3, 6, 9 and 10 to sampling adequacy. Also, cover <br />and production should be measured on the reference areas to <br />statistical adequacy in years 3, 6, 9 and 10. A report summing <br />up and analyzing the findings at that time would be required. <br />8. If the final pile is to have a flat area with an outslope, a <br />set of plots should be constructed to represent each of the <br />slopes. <br />9. Finally, the life of the plots must be ten years. They must be <br />protected from equipment and wind blown or water borne refuse <br />from the active portion of the pile. <br />If you have any questions, please feel free to call. <br />Sincerely, <br />.~ <br />Susan J.
